The latitude line that passes through the continent of Australia is the Tropic of Capricorn. This line of latitude is situated at approximately 23.5 degrees south of the Equator. It marks the southern boundary of the tropics and is named after the constellation Capricornus. The Tropic of Capricorn runs across the northern part of Australia, intersecting with the continent near the city of Rockhampton in Queensland. It plays a significant role in determining Australia’s climate, particularly in regions north of the line where the sun’s rays are more direct, resulting in warmer temperatures and distinct seasonal variations. Additionally, the Tropic of Capricorn serves as a geographic reference point, shaping cultural practices and geographical features across the continent. Its significance extends beyond Australia, influencing the climates and ecosystems of other countries and regions located within the southern tropics.
